For example, the decision about allowing gay marriage would create a big change in America. For this to be an effective change, many people will have to change the way they feel towards gay people. I am not saying that just because it gets approved that everything will be great and homophobia will no longer exist, but you have to start somewhere.
On another note, I would like to see a change when it comes to school violence. It is really upsetting to hear stories about a classroom that has been shot up or a child that has committed suicide due to bullying. I think there should be better security and counseling in these schools to prevent incidents like these from occurring. Without change, history tends to repeat itself and there are plenty of things from the past that we do not want to haunt us in the present.
